Application of Association Mapping to Understanding the Genetic Diversity of Plant Germplasm Resources
Figure 3
Linkage disequilibrium (LD) decay plot depicted from the LD values of a hypothetical marker data to demonstrate a measure of an average genome-wide LD block sizes. A pairwise LD values () are plotted against a genetic distance. Inner fitted trend line is a nonlinear logarithmic regression curve of on genetic distance. LD decay is considered below threshold and based on trend line it is around 38–40 cM in above plot. A pairwise LD between unlinked marker loci is assigned to 100 cM distance point. Note: this is for demonstration purposes only and does not have any real impact or correspond to any genomic fragment of an organism.
